Fodor's Expert Review Mesquite Flat Sand Dunes

These dunes, made up of minute pieces of quartz and other rock, are ever-changing products of the wind-rippled hills, with curving crests and a sun-bleached hue. Among the park's most photographed features, the dunes are at their best at sunrise and sunset. Keep your eyes open for animal tracks—you may even spot a coyote or fox. Bring plenty of water, and note where you parked your car: it's easy to become disoriented in this ocean of sand. If you lose your bearings, climb to the top of a dune, and scan the horizon for the parking lot.
